With the introduction of iOS 7, Apple added a ton of new and exciting features to your iPhone. However, in order to show off all of these new features, Apple has decided to turn them on: all of them. There’s an opt-out method (of sorts) when it comes to their use, but depending on the age of the device, this can decrease both performance and battery life. The problem most users are encountering is that they don’t know how to selectively opt-out of the features they do not use.
The following will outline how you can fine tune your iOS 7 experience, taking advantage of the features you like and turning off the features you don’t. In the end, you may find that you won’t need to charge your iPhone quite as often.
